--- Comment #90 from Karl Mistelberger
Using AMD Ryzen 3 3200G. In spring 2020 I was using Leap 15.1. To use built-in graphics I needed kernel newer than 4.12 from Leap 15.1. So I used kernels from kernel:stable repo. With Leap 15.1 + kernel 5.5.x suspend to RAM worked OK. With Leap 15.1 + kernel 5.6.x suspend to RAM stopped to work. Then I used kernel 5.3 for Leap 15.1 from Leap 15.2 developers repo to get suspend to RAM working. Now suspend to RAM is working OK with Leap 15.2 and standard 5.3 kernel.
I tried Leap 5.3.18-lp152.66-default and still get the following messages on suspend to RAM: Mar 13 09:46:17 Leap kernel: Non-boot CPUs are not disabled Mar 13 09:46:17 Leap kernel: amdgpu 0000:08:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test failed on gfx (-22). Mar 13 09:46:17 Leap kernel: [drm:process_one_work] *ERROR* ib ring test failed (-22). So I am wondering what your exact kernel version is. Mine are: i+ | kernel-default | package | 5.3.18-lp152.66.2 | x86_64 | Hauptaktualisierungs-Repository i+ | kernel-default | package | 5.3.18-lp152.63.1 | x86_64 | Hauptaktualisierungs-Repository i+ | kernel-firmware-all | package | 20201120-35.1 | noarch | (System Packages) -- You are receiving this mail because: You are on the CC list for the bug.
